A spark arrestor is a device intended to prevent combustible materials, usually sparks or other tiny flaming debris, from escaping into areas where they might start fires. They are most commonly used in conjunction with motor vehicles, as well as improving safety within fireplaces, and various electrical equipment.

"Tuberose (Polianthus) is a genus of plants of the natural order Liliaceæ. The plant is in high esteem for the beauty and fragrance of its flowers, the odor of which is most powerful after sunset. The fading flowers emit, in certain states of the atmosphere, an electric light and sparks. The native country of the tuberose is Mexico. They are very extensively grown by American and British florists, who, by planting the roots successionally, manage to keep up a supply of flowers at all seasons. There are several varieties."—(Charles Leonard-Stuart, 1911)
